The RS485 circuit controls the Input and Output direction automatically, there’s no need to control it from
within the software.
The default product without the CM4 does not include a Wi-Fi/BT module. You can include a CM4 that has the
Wi-Fi/BT module at the Chipsee store during the ordering process.
This TF card is designed for storage expansion, as the TF card uses the same pins with WiFi, it can’t be used

Power Input
The PPC-CM4-190 industrial Pi PC can be powered by a wide range of input voltages: From
12V to 36V DC. It is a 3 Pin, 3.81mm screw terminal connector. As shown in the gure
below.
Power Input
Note that the “+” sign represents the positive power input, and it is printed both at the
casing and as a silk-screen on the board of the embedded version. The “-” terminal is
shorted to the ground.

Touch Screen
The PPC-CM4-190 industrial Pi PC uses a 10-point capacitive touch with 1mm Armored Glass
screen. However, the Raspberry Pi OS supports only One-Point touch.
The gure below shows the capacitive touch screen connected to the motherboard via the
USB connector.
Capacitive Touch Connector
Attention
A capacitive touch screen is susceptible to power noise and Electromagnetic Radiation (EMR). It may cause LCD ripples
or even capacitive touch malfunction. If using a capacitive multi-touch test application, you might notice the touch
points oat erratically across the display. There are several solutions to this problem:
Use a high-quality Power Adapter Unit (PSU) with low EMR. You can also provide power from a battery.
Make sure that the PPC-CM4-190 Power Input connector (pin 3) is properly connected to the Power System
Ground to provide sucient EMI shielding and eliminate the problem entirely.
Bad GND problems can also be conrmed by touching pin 3 of the Power Input connector with one hand while
operating the capacitive touch screen with the other hand. In this case, the operator’s body acts as the Power
System Ground.

Connectivity
There are many connectivity options available on the PPC-CM4-190 industrial Pi PC. It has 2
x USB 3.0 Host, 1 x USB OTG, 1 x Channel Giga LAN (RJ45) Ethernet connector supporting up
to 1 Gbps, and 4 x UART and 1 x CAN terminals (RS232/RS485/CAN).
RS232/RS485/CAN
The serial communication interfaces (RS485, RS232, and CAN) are routed to a phoenix
terminal, as illustrated in the gure below.

The table below oers more detailed description of every pin and its denition:
Attention
RS485_3 and RS485_5 can control the input and output direction automatically. There’s no need to control it from
within the software.
The 120Ω match resistor for RS485 is already mounted by default.
The 120Ω match resistor for CAN is NOT mounted by default. Be sure to mount the match resistor when testing
CAN.
The 2 x RS485 can be congured to 2 x RS232, if you want a custom conguration, you can contact us when
placing an order.

GPIO Port
The PPC-CM4-190 industrial Pi PC has a phoenix connector, as shown in the gure below.
The table below gives details about the denition of every Pin.
Isolated GPIO reduced schematic
Attention
In order to use the Isolated Output, you need to add an external Isolated Power to the VDD_ISO and GND_ISO.
The power voltage should not exceed 24V.
The output current can achieve 500mA for every channel, but it also depends on the isolated power that is
connected.
In order to use the Isolated Input, you need to add a signal to the ISO_InputX and GND_ISO. A 2.4KΩ resistor, as
R6, can be added to limit the input current, as shown in the gure above. This resistor should work well for the
5-24V input signal. If your input signal is less than 5V, please change this input resistor.

USB Connectors
There are 2 x USB 3.0 Host, 1 x USB OTG onboard, as shown in the gure below.
USB HOST Connectors
The product has one USB Type-C OTG connector that works as a slave by default. You can
use it to establish a connection with the host PC and for downloading the system to the
eMMC of CM4 module.
USB Type-C OTG Connector
Attention
1. These two USB host connectors can drive 500mA for each channel at most.

Warning
Be careful not to touch surrounding electronic components accidentally while plugging in USB devices into the
embedded Industrial PC version.
Remember to unplug the Type-C cable after ashing OS, otherwise the USB hosts won’t work.
